Features of promising technologies for pretreatment of lignocellulosic biomass.
This paper reviews process parameters and their fundamental modes of action for promising pretreatment methods and concludes that pretreatment processing conditions must be tailored to the specific chemical and structural composition of the various, and variable, sources of lignocellulosic biomass.
Pretreatment: the key to unlocking low‐cost cellulosic ethanol
New transportation fuels are badly needed to reduce our heavy dependence on imported oil and to reduce the release of greenhouse gases that cause global climate change; cellulosic biomass is the only
Coordinated development of leading biomass pretreatment technologies.
Comparative data were developed on sugar recovery from hemicellulose and cellulose by the combined pretreatment and enzymatic hydrolysis operations when applied to corn stover through a Biomass Refining Consortium for Applied Fundamentals and Innovation (CAFI).
How biotech can transform biofuels
For cellulosic ethanol to become a reality, biotechnological solutions should focus on optimizing the conversion of biomass to sugars.
Physical and chemical characterizations of corn stover and poplar solids resulting from leading pretreatment technologies.
In order to investigate changes in substrate chemical and physical features after pretreatment, several characterizations were performed on untreated (UT) corn stover and poplar and their solids
BIOMASS ETHANOL: Technical Progress, Opportunities, and Commercial Challenges
▪ Abstract Ethanol made from lignocellulosic biomass sources, such as agricultural and forestry residues and herbaceous and woody crops, provides unique environmental, economic, and strategic
Lignin Valorization: Improving Lignin Processing in the Biorefinery
Recent developments in genetic engineering, enhanced extraction methods, and a deeper understanding of the structure of lignin are yielding promising opportunities for efficient conversion of this renewable resource to carbon fibers, polymers, commodity chemicals, and fuels.

The results suggested that BSA treatment reduced adsorption of cellulase and particularly beta‐glucosidase on lignin and identify promising strategies to reduce enzyme requirements for cellulose hydrolysis.
Combined sugar yields for dilute sulfuric acid pretreatment of corn stover followed by enzymatic hydrolysis of the remaining solids.
Individual xylose and glucose yields are reported as a percentage of the total potential yield of both sugars over a range of sulfuric acid concentrations to suggest that enhanced hemicellulase activity could further improve xylOSE yields, particularly for low cellulase loadings.
Lignin content in natural Populus variants affects sugar release
Factors beyond lignin and S/G ratio influence recalcitrance to sugar release are suggested and point to a critical need for deeper understanding of cell-wall structure before plants can be rationally engineered for reduced recal citrance and efficient biofuels production.
